eb3596f7c2 Do not add random inbound peers to addrman.
We should learn about new peers via address messages.

An inbound peer connecting to us tells us nothing about
 its ability to accept incoming connections from us, so
 we shouldn't assume that we can connect to it based on
 this.

The vast majority of nodes on the network do not accept
 incoming connections, adding them will only slow down
 the process of making a successful connection in the
 future.

Nodes which have configured themselves to not announce would prefer we
 not violate their privacy by announcing them in GETADDR responses.

Merge #8282: net: Feeler connections to increase online addrs in the tried table.
dbb1f64 Added feeler connections increasing good addrs in the tried table. (Ethan Heilman)

dbb1f640e6 Added feeler connections increasing good addrs in the tried table.
Tests if addresses are online or offline by briefly connecting to them. These short lived connections are referred to as feeler connections. Feeler connections are designed to increase the number of fresh online addresses in tried by selecting and connecting to addresses in new. One feeler connection is attempted on average once every two minutes.

This change was suggested as Countermeasure 4 in
Eclipse Attacks on Bitcoin’s Peer-to-Peer Network, Ethan Heilman,

96fa95361f Improve handling of unconnecting headers
When processing a headers message that looks like a block announcement,
send peer a getheaders if the headers message won't connect.

Apply DoS points after too many consecutive unconnecting headers messages.
